As a reminder, the second episode of “All Access: Ronda Rousey” airs tonight on Showtime.

The second half-hour special provides a behind-the-scenes look at the Strikeforce women’s bantamweight champion ahead of her Saturday title fight with former titleholder Sarah Kaufman.

Tonight’s episode airs at 9:30 p.m. ET/PT and takes a look at Rousey’s training for Kaufman. The first episode aired this past week and can be viewed in its entirety at MMAjunkie.com.

Rousey (5-0 MMA, 3-0 SF) looks to defend her title for the first time since winning it from Miesha Tate in March when she meets Sarah Kaufman (15-1 MMA, 6-1 SF) at “Strikeforce: Rousey vs. Kaufman” at Valley View Casino Center in San Diego. It’s Rousey’s second straight main-event fight for Showtime.

Showtime cameras have followed Rousey, an Olympic bronze-medal judoka, in and out of the cage, and the above preview clip focuses on her training for Kaufman. This past week’s first episode went behind the scenes of Rousey’s photo shoot for “ESPN The Magazine’s” Body Issue, which recently hit newsstands. Rousey was one of six athletes chosen for commemorative covers.

Replays of “All Access” air on Showtime, Showtime Extreme and Showtime On Demand throughout the week.

UFC women’s bantamweight champion Ronda Rousey is probably the greatest female fighter on the planet, which is a tremendous feat. So why are we seemingly so obsessed with arguing about whether she could beat up men?
